GE SVi 1000 Masonelian Quick Start Manual page 83

Ci = 4 nF
Li = 10 uH
7.5 SVi1000 (+) and (-) Position Retransmit (4-20mA Output) Terminals
These terminal provide the 4-20mA position retransmit output and are equipped only on the
Position Retransmit Terminal board. A transmitter type barrier with 250 Ohm series resistance
(internal or external) could be used for this connection.
Entity Parameters:
Vmax= 30 Vdc
Imax=125 mA
Pmax = 900 mW
Ci = 8 nF
Li = 1 uH
7.6 Entity Requirement
Cable capacitance and inductance plus the I.S. apparatus unprotected capacitance (Ci) and
inductance (Li) must not exceed the allowed capacitance (Ca) and inductance (La) indicated
on the associated apparatus. If the optional Hand Held Communicator is used on the
Hazardous Area side of the barrier, then the capacity and inductance of the communicator
must be added and the communicator must be agency approved for use in the hazardous
area. Also, the current output of the Hand Held Communicator must be included in the
current output of the associated equipment.
The barriers may be active or passive and from any certified manufacturer as long as the
barriers comply with the listed entity parameters.
7.7 Installation Restriction
A device which has previously been installed without an approved IS barrier must NEVER be
used subsequently in an intrinsically safe system. Installing the device without a barrier can
permanently damage the safety related components in the device making the device
unsuitable for use in an intrinsically system.
